Abstract

Signaldetektor (1) zur Detektion eines Biosignals mit annähernd bekannter Morphologie in einem komplexen Eingangssignal (ECG), insbesondere zur Detektion von QRS-Komplexen in einem Elektrokardiogramm, mit Mitteln (10A) zur Erfassung der maximalen Amplitude (PEAK) des detektierten Signalkomplexes innerhalb eines vorgegebenen Zeitfensters, einem Schwellwertdiskriminator (14), einer Detektorparameter-Vorwahlschaltung (11) zur Bestimmung eines Initialwertes eines die Detektionsempfindlichkeit kennzeichnenden Detektorparameters, der den Detektions-Schwellwert (TH) bestimmt, im Ansprechen auf ein Detektionssignal und in Abhängigkeit von maximalen Amplitude und einer Detektorparameter-Zeitsteuerschaltung (11, 12A) zur Einstellung einer vorbestimmten Zeitabhängigkeit des Detektorparameters und damit des Detektions-Schwellwertes, wobei die vorbestimmte Zeitabhängigkeit mindestens in einem ersten Zeitbereich eine stufenartige Verringerung des Detektions-Schwellwertes bis höchstens zu einem in Abhängigkeit von der maximalen Amplitude bestimmten unteren Grenzwert und/oder in einem zweiten Zeitbereich eine stufenartige Erhöhung bis höchstens zu einem in Abhängigkeit von der maximalen Amplitude bestimmten oberen Grenzwert mit vorbestimmten Stufen (STEPS) einschließt.
